Also, I know the newer versions of this engine have VVT-i on the exhaust cams as well. That brings up another question - could using a different viscosity than what is specified cause any issues with that dual VVT-i setup?
My understanding is that the only difference is the vvt on the exhaust. Pre-2010, this engine was spec'd 5w30, and after much reading of FJ forums there are a lot of guys post 2010 using 30 weights with no issues. Plus as mentioned, thicker oil is actually recommended in the manual. I've been unable to find any reference to clearances or oil drain hole sizes changing....so IMO it is for CAFE.

I'm with CT.OEM filter too.

Which on list have builder approvals -vs- self recommendation?
0w20 or 5w20 until perhaps 100k miles. Then 5 or 10w30. That what I would do

Very nice! ^^^^^^^^^^^^^^^^Especially for 06

Any votes for Schaeffers 0w-20?
Any votes for Amsoil 0w-30?
I am concerned about Mobil1 0w-20 or 0w-30 as Zn and P is lower with the Adv. Fuel Economy formulations.
Since I will change it once a year I am not too worried about price.

Out of those choices, M1.
Anything from Mobil 1afe 0w20 to 0w40. Any quality brand of api SN oil is fine choose viscosity based on service.
I have 0w40in my 2018:and 0w20 in the 2017. Based on how they are used.
For those asking what changed with the oil recommendation, with the dual vvti versions..
New cooling jacket spacers in the head were to allow lower viscosity oils to perform in this engine this allowed better temperature control around the combustion chamber.
Also the bucket cam followers were replaced with roller followers that have hydraulic lash adjustment (no more mechanical valve adjustment needed.), there was also some optimization of the crankcase counterweights. The piston oil squirters, aluminum grooved crank and journal bearings remain. The configuration of the dual vvti made it neccesarily to move the oil filter location to the inconvenient location where skid plate removal is required to replace an oil filter.

Either Schaeffer or Amsoil are a great choice IMHO.
Not too crazy on M1.

I am looking at a 1 year/4000-8000 mile oil change interval.
For that engine, which is very popular in Australia, both Valvoline & Castrol say to use a 5W30 synthetic or a 10W30 semi-synthetic.
That is probably what I would do too.
We get a nice full synthetic Castrol Magnatec 5W30 that is American API SN and Euro ACEA A3/B4. That is what I would probably use.

Unfortunately the prevalence of ACEA a3 certified 30wts is limited in the USA.
Most easily available A3 lubes are in the 0w40 variety. The 5w30 Castrol Magnatec here is a resource conserving oil with lower additive levels.

It's not worth the effort for inferior product that's harder to find and costs more.
I've run various in my 2018 4Runner SR5P. In it now is M1 EP 5w30. Might switch to a 0w20 this winter. Might not. 93K on it now.
I’m kinda surprised here…. When I bought our used v6 3.5 Lexus, it was pretty noisy. It calls for 0-20 but Ive run 5-30 PUP in it and it’s done well with that. Walmart had a good sale here with M1 5-20 EP, so i figured I’d give that a run. It took the full 5 qt jug of 5-20, and needed another quart, which was 10-30 from the 2 jugs bought for the truck. It’s just as quiet, and is markedly holding higher gear/ lower rpm’s than before without a change in driving habits (I keep it in eco mode). For whatever reason, this particular combo seems to do well with M1 Ep 5-20. I’ve not used M1 in many years, but am liking how it’s working right now. May go back and get more while that sale is on.
These engines aren't picky about grade.
They'll run forever on anything.
I'm currently running M1 ESP 0W-30 that I got on sale for $29/5 qt over at AAP in my 07 Tacoma 1GR-FE "Gen 1" with over 250,000 miles (will run for around 8K, then check the level - it tends to be slightly low after that many miles), and M1-EP 10W-30 in my wife's 2021 4Runner (will run for 10K)
